  • Application of NPTF thread NPTF is the thread for sealing pipes without using any sealing material. Thread symbol is similar to NPT but the tolerance is different from that of NPT, therefore the above inserts are not available for NPTF.

  • TM thread: TM thread (old JIS 30˚ trapezoidal thread) has been discontinued. But if the "Nominal dia. X pitch" is the same, the above Tr thread can be used.
  • TW thread: TW thread is 29˚ trapezoidal thread, therefore the above inserts are not available.
